Unless you cut wires and then put quick disconnects on them, thereby negating the need for future cutting, you will need to cut wires to make the install.

I realize that different jurisdictions have different laws about who can run what, where, and why, but...the first question that springs to my mind is that if you have a legitimate need for such flashers, how come you don't have your agency's fleet shop advise you on such matters, and/or do the job for you?

All members on are department allow red lights and flashers..The city takes no responsibility for injuries if you have them. The department says you are on your own for installs. I have always had them. Thanks for the help

Damn, that stinks! Ask around on the department, somebody must be quite skilled with making the correct installations then...or have a connection in the area who can help you.

Usually it involves splicing into the headlight wiring harness, running wires to the relay box, mounting the flasher relay box under the hood, then running wires to a switch in the cabin. However I have also seen units where the relay(s) and switch are in a box mounted in the cabin, with just the wires leading under the hood.
